As I was trying different utilities and wasn't seeing anything on my outside card I then decided to disconnect my gateway machine. The high traffic continued. I called my ISP and they told me to run tcpdump and send it to them. A few minutes later the activity was way down. Looks normal now. I still plan to go through all the tools and learn them, but whatever the problem is/was it was not inside my machines/network. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

/usr/ports/net/trafshow -Original Message- From: Francisco Reyes [mailto:[EMAIL PROTECTED] Sent: Thursday, March 04, 2004 5:45 AM To: FreeBSD Questions List Subject: Monitoring TCP/IP traffic As of a few days ago my DSL modem activity light rarely ever goes inactive for long. I am looking for any program anyone could recommend to monitor what's going on. Yesterday I added log options to all my IPFW rules to see if I could find anything suspicious. I added log options even to pass rules and the amount of activity in the DSL modem seems much more than what is reported by IPFW rules. The machine in question is a 4.9 Stable (as of Dec 29) and it acts as a gateway to my other machines. Is there is anything like TOP for TCP/IP?

You need to tweak its configuration t make it listen on the tun0 interface. Take a look at ngrep too. and snort fr logging suspicious activity.
